Causes
The cause isn't known, but limited scleroderma is believed to be an autoimmune disorder, in which your immune system turns against your body. The immune system appears to stimulate the production of too much collagen, a key component of connective tissue. This overproduction of collagen builds up in the skin and internal organs so that they don't function normally.
